The mirrors don't shake. The car is small. I wouldn't want to get hit by anything at high speed, but I used to own a Toyota Landcruiser and I got rear ended at high speed by a VW beetle and my car was a mess. My back hurt, we were thrown violently backwards, and that darn VW didn't even have the airbags deploy, and the driver was fine. So I learned alot about well built small cars that day. But I also learned you don't want to get hit by anything. So I drive defensively, watch out for nuts, and try to have a good time and not worry too much.
